JOHN'W-ENGS, oFMoNRoE; MICHIGAN.

Be it known that 1, JOHN WENGS, a citizen of the United States of America, residing at l Monroe, in the county of Monroe and State of M chigan, have invented certain new and useful. Im rovements in Molds for Making 'Buildinglocks, of which the following is a specification, reference being had therein to t e accompanying drawings.

,mThis invention relates to improvements in molds for forming building or other blocks from cementitious material; and the object of the invention is to provide a mold which is so constructed that the block after being formed therein may be expeditiously removed therefrom without danger of injury to the block and in such a manner as to make .it readily accessible for carrying away.

It is also an object of the invention to so make the mold that it may be readily adjusted to increase the length, width, or thickness of the block and so that a carrier-board may be used to form the side or edge of the block and the block released from the mold with either its side or edgedownward in the desired position fordrying.

To this end the invention consists in mounting the mold to turn bodil upon pivotbearings, so that after being fill may be swung downward to an inverted position and the block released, and by employing a carrier-board to form one side of the Y mold the mold may be turned to bring said side downward and the block then released, thus leaving the block in position upon the carrier-board.

The invention further consists in the particular construction,v arrangement, and combination of parts, all as hereinafter more fully described, reference being had to the accompanying drawings, in wh1ch- Figure 1 is a front elevation of a device embody ng the invention with parts broken away to show the construction Fig. 2, an'end elevation of the same; Fig. 3, a rear elevation and Fig. 4 a transverse vertical section on the line :10 a; of Fig. 1 and showing the mold-box turned to its inverted position and in dotted lines turned to its horizontal position.

As shown in the drawings, a suitable'suporting-bench is formed by end frames or egs 1 and a plank'2, forming theto secured to the upper ends of said frames. xtending laterally from the end frames at their upper ends are brackets forming bearings 3 for a longitudinally-extending shaft 4, provided shaft. Ears are ed the mold MOLD FOR-MAKING .B UlLblN G-BLOOKS. V

with a handle-lever 5 at one end, by means of which the shaft may be easily turned;

6 is the bed-plate of the mold-box and 1s firmly secured to the shaft 4'by means of bolts 7, sleeves 8 onthe bolts being interposed between the shaft and plate to hold the plate at a distance from the shaft, so that it will clear the bearing in turning with the rovided on the end and rear edges of the ed-plate, and similar ears are rovided on the end lates 9 and rear side i wal 10 of the mold, formlnghin es to connect. said end plates and wall to t e bed-plate.

The front side of the mold-box is formed by bolting two brackets 11 .to the bed-plate and lacing inside of these brackets a lank or Board 12 against the ends of the a justinge screws 13, which extend through openings 1n the brackets and are adjustably secured therein by lock-nuts 14, so that the board 12. will be held at the desired distance from the brackets to give the required thickness of, cement block.

15 is a movable bottom facing-plate for the mold roper, which bottom is held in place by bo ts 16, extending loosely throughopenings in the bedlate, so that it may drop a short distance-W en the mold is inverted and the block released, and 17 represents adjustable end facing-plates for the mold, which are adjustably secured to the end plates 9 by ad. justing bolts or screws 18 extending through 0 enings in said ends and adjustably secured t erein by lock-nuts 19, the end facing-plates being secured to and supported by the inner ends of said bolts. These end facing-plates may then be easily and accurately adpisted to vary the length of the blocks and move with said ends when the samev are turnedon their hinges to release the molded block.

A s ring 20 is attached at one end to each end p ate and at its opposite end to an arm extending outward from the end of the bedplate and exerts a force to normally turn the end plates outward on their hinges, so that the mold ends will be automatically turned away from the molded block as soon as said 1 ends are released by disengaging the hooks 21, pivotally attached to the rear mold-wall 10, from the pins 22, extending outward from the ends-of the arms 23 on the end plates, which arms extend l longitudinally, of the mold from the rear edgesof said end plates and are adapted to engage the outer surface of said rear wall when the mold is closed.

The bearings 3 are at one side of thebenchtop 2, and the mold is secured to the shaft 4 at one side of the longitudinal center line of its bed-plate, so that when the mold is in its normal fposition for filling it is supported by 5 the sha t at one side of its center line and at its opposite edge by the bench-top. The tendency of the mold to turn on its bearings while in this position is thus removed, and the mold is firmly supported without the necessity of securing the same in that position.

After the cement has been thoroughly tamped into the mold .a cover to hold it in place while the mold is being turned to the position shown in full lines in Fig. 4 is provided, consisting of a board or plank 24, held in place by bars 25, ivotally attached at one end to the rear wall of the mold and at their opposite ends engaged by hooks 26,

2o pivotally secured to the brackets 11 at the front side of the mold. This board 24 preferably serves as a carrier-board upon which the molded block is removed and set away to dry. To support the board when released 25 from the mold by disengaging the hooks 26 and 21 and turning the mold-wall 10 back, as shown in dotted lines in Fig. 4, any suitable vertically-adjustable support 27 which may be raised into engagement with the board 0 and then lowered to lower the block when the same is released may be employed.

It is often desirable to divide the mold into two parts by a division-wall, as shown by the dotted lines 28 in Fig. 4, and when 3 5 the wall is placed to divide the mold horizontally the mold is turned to the position shown in dotted lines and the molded blocks released, so that the division-wall may be removed from between the blocks edgewise.

The board 12, which forms the front side of the mold, would in this instance serve as the carrier-board for the blocks. With this construction the mold-bottom may be shaped to form a rock-face on that edge of the block as the block is inverted by the turning of the mold and set upon its smooth opposite edge, and a very inexpensive, compact, and easily adjusted and operated device is secured.

Having thus fully described my invention,

what I claim is 1. The combination with a mold-box, of a bench for supporting the mold-box having a top, bearing-brackets on the bench extending laterally therefrom, a shaft rotatable in said bearings at one side of the top, means for securin the mold-box at one side of its longitudina center line to the shaft to turn therewith, said box being adapted to rest upon said top when in its vertical position and be supported by said top and shaft, and means for turning the shaft. 7

the mold-bottom at one side of its longitudinal center line and extending through openings in the shaft, sleeves on the bolts for spacing the mold-box from the shaft, and

means for turning the shaft.

3. In a mold, the combination with a bedplate and sides attached to said bed-plate, of end plates hinged to the bed-plate, facingplates inside the end plates, adjusting-screws extending through the end plates and secured to the facing-plates to adjustably support said facing-plates, and coiled springs attached to the base-plate at one end and to the end plates at their opposite ends to normally hold said ends turned outward on their hinges.

4. In a mold, the combination with a bedplate, of a side and ends hinged to said bedplate, brackets secured to the bed-plate oposite the hinged side, a detachable board forming the opposite side, adjusting-screws extending through the brackets and engaging the board, a movable bottom facingplate, arms on the ends adapted to engage the outer surface of the hinged side and provided with outwardly-extending pins, and hooks on the hinged side to engage said pins.

5. In a mold, the combination of a bench having laterally-extending bearings, a shaft in said bearings, a bed-plate, bolts extending through said shaft to secure the bed-plate thereto, sleeves on the bolts between the shaft and bed-plate, brackets secured to one edge of the bed-plate, a mold-wall hinged to the opposite edge of said bed-plate, a movable facing-bottom, bolts on the facing-bottom extending through openings in the bedplate, a board forming the side wall of the mold enga ing the brackets, ends hinged to the ends of the bed-plate, facing-plates, adjusting-screws on the ends secured to and supporting said facing-plates, arms on the ends engaging the outer surface of the hinged side wall, pins on said arms, hooks on the side wall engaging said pins, outwardly-extending arms on the ends of the bed-plate, springs attached at one end to said arms and at their opposite ends to the mold ends, a top board, and means for securing the top board in place.

In testimony whereof I aflix my signature in presence of two witnesses.
